We present the first demonstration of an Yb:CALGO thin-disk laser. In a slightly multimode configuration we obtained up to 30 W of average power at a slope efficiency of 40% and an optical-to-optical efficiency of 32%. With a single-mode cavity, an average power of 25 W was achieved. A tuning range from 1018 to 1052nm could be demonstrated by inserting a prism into the cavity. In Q-switched regime, we obtained 1 mJ of pulse energy at a repetition rate of 100 Hz.
